Efficacy of surgical treatment of patients with localized gastrointestinal stromal tumors

Abstract

The main method of the treatment of patients with localized and locally advanced gastrointestinal stromal tumors (GIST) currently remains to be surgical, but its effectiveness is limited and determined by the degree of local expansion of the disease and radicality of the surgery. Before the era of the use of tyrosine kinase inhibitors (TKI) in the treatment of GIST patients the overall 5-year survival after radical surgery in the group of patients with size of the tumor larger than 10 cm failed to exceed 20%. For the time present with the comprehensive approach to the treatment indices of survival in these patients have significantly improved. Overall 5-year survival in patients with a high risk of disease progression reaches 93%. The most important prognostic factors in patients with primary localized GIST are: the size of the primary tumor, mitotic index, tumor location, mutation status and the morphological variant of the cellular structure of GIST.
